-    These two properties allow an author or user to require that an element's font size be clamped
-    within the specified range.
-    If the specified value 'font-size' is outside the bounds created by
-    the used 'font-min-size' and 'font-max-size',
-    the computed value of 'font-size' is clamped to the values specified in these two properties.
-
-    If the computed 'font-min-size' is larger than the computed 'font-max-size',
-    then the used 'font-max-size' is increased to match the 'font-min-size'.
-
-    Some user agents provide a non-standard mapping between the computed value of 'font-size' and the used value of 'font-size'.
-    The interaction of those nonstandard algorithms with 'font-min-size' or 'font-max-size' is explicitly undefined.

-    Note: Users with accessibility preferences can set these properties
-    as ''!important'' rules in a <a>user style sheet</a>
-    to force websites‘ text to become larger or smaller.
